Ahmed Al-Maadheed';s Full name is
"AHMED BIN MAJED ALMAADEED"
It is a simple guess how the word "Majed" got associated with Tamim's name.
Tamim name (in Bold) ...and on the side Artist name (not in Bold)..

Even the artist's facebook account is @ahmedbinmajedwork

But Sheikh Tamim is wonderful , and we all love him
